2 Tuesday, April 14, Southeast Florida Status of Model Development Through the rough water of software migration Through the rough water of software migration Actively using Cube/Voyager based SERPM 6.0 and TCRPM III Actively using Cube/Voyager based SERPM 6.0 and TCRPM III

3 Tuesday, April 14, Models under Constructions SERPM 6.5 SERPM 6.5 Miami-Dade, Broward, Palm Beach Miami-Dade, Broward, Palm Beach Use “Tier D” Transit Model Framework Use “Tier D” Transit Model Framework GTCRPM III (Greater Treasure Coast Regional Planning Model) GTCRPM III (Greater Treasure Coast Regional Planning Model) Palm Beach, Martin, St. Lucie, Indian River and part of Brevard (south of S.R ) Palm Beach, Martin, St. Lucie, Indian River and part of Brevard (south of S.R ) Highway Only Highway Only Base Year: 2005 Base Year: 2005

4 Tuesday, April 14, Key Features More Accurate Representation of “Supply” Models: More Accurate Representation of “Supply” Models: Transit: Applied “Tier D” Framework, (e.g., station micro coding) Transit: Applied “Tier D” Framework, (e.g., station micro coding) Highway: Use physical attributes (e.g., posted speed & signal spacing) to calculate link initial speeds and capacity Highway: Use physical attributes (e.g., posted speed & signal spacing) to calculate link initial speeds and capacity Land Use: Calculated intensity instead of assigned AT Land Use: Calculated intensity instead of assigned AT

5 Tuesday, April 14, SERPM 6.5 Production Plan Developing 2030 Model for Production Developing 2030 Model for Production Validate 24 Hour Version: by December 2007 Validate 24 Hour Version: by December 2007 For Miami-Dade, Broward, Palm Beach MPOs’ 2035 LRTP Updates For Miami-Dade, Broward, Palm Beach MPOs’ 2035 LRTP Updates Running Time: Approximately: 7 hours on 4-cores Running Time: Approximately: 7 hours on 4-cores Validate Time-of-Day Version: by April 2008 Validate Time-of-Day Version: by April 2008 For Major Investment Projects For Major Investment Projects Develop (24-HR) Sub-Area Versions: by June 2008 Develop (24-HR) Sub-Area Versions: by June 2008 For local projects and site impact analyses For local projects and site impact analyses
